how to create a html form using PHP 7 to send data to a mysql database?

Is it really diferent from PHP 5...

I have this code that gives me a Parse error: syntax error, unexpected 'New' (T_NEW) in /home/u670931909/public_html/php.php on line 16

PHP code:

<?php
$co = new mysqli(DB_HOST, DB_USER, DB_PASSWORD, DB_NAME);
if ($co->coect_error) {
die("Coection failed: " . $co->coect_error);
}
$value = $_POST['name'];
$value2 = $_POST['message'];
$sql = "INSERT INTO js (userName, userMessage) VALUES('$value', '$value2');
if ($co->query($sql) === TRUE) {
echo "New record created successfully";
} else {
    echo "Error: " . $sql . "<br>" . $co->error;
};
$co->close();
?>
